Title: Seal for joint line between core box halves - obtd. by casting elastomer sealing rail in groove surrounding cavity in core box
Inventor: FISCHER ERWIN
IPC: B22C7/06
Filed: 1980-07-25
Abstract: The core box consists of two or more halves; and at least one completed half is provided with a groove round the edge of the cavity which will be filled with sand or other material to make cores. The master core pattern is placed in the cavity; and the core box is assembled using a spacer to separate the box halves. A rubber-elastic mass is poured or sprayed into the groove and sets to form an elastic sealing rail. Due to the spacer, the sealing rail projects above the groove to form an effective seal during core-blowing. The groove may form pary of a cast core box, or be milled in the box. Esp. in blowing sand cores which may have a complicated shape.

Title: Closed transportable hopper for free-flowing material - has suspension points each side defined by centre of gravity
Inventor: SCHOLZE RICHARD D ING GRAD
IPC: B60P1/48
Filed: 1980-10-31
Abstract: The closed hopper for free-flowing material is mounted on an underframe allowing extraction of the contents from underneath, while it can be transported in the horizontal position and loaded and unloaded by a suitable vehicle. On each side of the hopper are two suspension points. The positions of the latter are defined by a triangle, whose height and base length are variable. The base of the triangle is on the lengthwise axis of the hopper, and is bisected by a perpendicular to this axis, through the centre of gravity. The apex of the triangle coincides with the attachment point of the hydraulically-operated lifting arm on the vehicle to the chains leading to the suspension points, which can be set at any position on the triangle sides or one extension of them, the rearmost of them in the horizontal position being however preferably above the lengthwise axis. This prevents the hopper tipping over on setting down from the vehicle in the upright position.

Title: Gasification of organic wastes - and use of energy of prod., gases for electricity generation and district heating
Inventor: HUMMELSIEP HORST DIPL ING DR I
IPC: C10J3/20
Filed: 1980-12-20
Abstract: Carbonaceous waste is processed by gasification. Heat passes from the prod. gas to the water used in washing it, and thence (pref. after raising the temp. in a heat pump) to the working medium of a district heating system. The prod. gas is then burnt under pressure in a gas turbine, driving an electricity generator. The exhaust gas from the gas turbine is used to raise superheated steam to drive a steam turbine, and so to generate more electricity. Part of the heat of the prod. gas can be used to preheat the waste before this pressing. Tar and oil removed from the prod. gas can be recycled to the gasifier or added to the waste being prepd. for gasification. The energy available in the waste is used optimally and economically.

Title: Process for the continuous preparation of polymers
Inventor: THIELE REINER PROF DR
IPC: C08F2/06
Filed: 1981-05-04
Abstract: The continuous preparation of homopolymers, copolymers and graft polymers of styrene by bulk polymerisation with or without the addition of a solvent in a stirred reactor cascade with intermediate feeding of monomers and other reactants calculated on the basis of a closed process model using the principle of forward control. The invention has the object of carrying out the process in such a way that polymerisation products having any desired molecular and chemical uniformity can be produced with at the same time high monomer conversions of greater than 80% being achieved. This is achieved by using a novel, closed reactor model for interchangeable initiation mechanisms, modelling to the limiting conversion and the incorporation of the gel effect. This makes it possible, by suitable temperature control and intermediate feeding into the individual reactors, to achieve a process regime which allows the preparation of polymers having the desired structural parameters.

Title: Device for the lateral stabilisation of the lower links of an appliance-mounting apparatus of commercial vehicles which can be used for agriculture and/or forestry
Inventor: STEMMER JOSEF
IPC: A01B59/041
Filed: 1981-07-27
Abstract: What is described is a device for stabilising the lower links of an appliance-mounting apparatus of a motor vehicle which can be used for agriculture and forestry, by means of which device either an absolutely rigid fixing of the lower link or an elastic force centering of the lower links can be ensured simply by throwing over a blocking means. It is thereby possible to fix the lower links in a predetermined position, without any braces between the lower links, and at the same time, when work units are coupled to the appliance-mounting apparatus, to ensure a reliable centering of the lower links, so that care is taken to ensure that, even when heavy work units are raised by means of the lifting arms, a reliable centering of the work unit is guaranteed. In this way, the mass forces caused by transverse accelerations are effectively absorbed, so that the driving behaviour of the tractor is improved and damage to the three-point mounting and to the stabilising device is avoided.

Patent DE-3138117-A1 (DE)
Title: Section monitoring device
Inventor: KRUG ADOLF DR ING
IPC: G01S13/62
Filed: 1981-09-24
Abstract: On a track-guided vehicle (F), two response devices (A1, A2) are arranged in each case and send a response signal to an interrogating device (AB) in accordance with an item of information in each case associated with them. The planes of polarisation of the two response signals are perpendicular to one another in this arrangement. In the interrogating device (AB), which can separately recognise the two response signals, the information items can be combined to form a total vehicle-specific information. The response devices (A1, A2) are arranged at such a distance from one another that they pass with overlap through the area of influence of the antenna (AT) of the interrogating device (AB). The successive recognition of the response signals with a different plane of polarisation supplies a criterion about the direction of passage of a vehicle (F) compared with the location of the interrogating device (AB) and thus also of the state of occupancy of the two track sections (I, II) adjoining the section points. <IMAGE>

Title: Fusible conductor and method of producing it
Inventor: SCHULTZ LUDWIG DR
IPC: H01H85/055
Filed: 1981-12-02
Abstract: A fusible conductor for a fuse device, in particular for a semiconductor fuse, comprises a thin conductor element composed of a nobler metal which is situated in a narrow region between at least two conductor sections containing baser metal. It is intended that such a fusible conductor should be relatively simple and cheap to produce and nevertheless contain only a relatively small proportion of the nobler metal. The invention provides for the fusible conductor (21) to contain a conductor element (13) extending over its entire length (L) and composed of the nobler metal, which conductor element is connected outside the at least one narrow region (23) on at least one side to the baser metal of the conductor sections (22). Said fusible conductor (21) can advantageously be produced by first producing a conductor preproduct containing at least one conductor part composed of baser metal and one conductor part composed of nobler metal, then deforming said conductor preproduct so as to produce a composite conductor and, finally, removing, for example etching off, the baser metal at the planned narrow region (23) of said composite conductor. <IMAGE>
